How long are the dietary taboos for rabies vaccine?

At present, it is generally recommended in clinical practice that the dietary taboos of rabies vaccine should cover the entire vaccination cycle, and can be lifted 7 days after the last injection. Calculating based on the conventional 5-injection method, the total is about 35 days. There is no need to deliberately avoid food for too long.

I have been working as a community vaccination worker for almost 7 years, and I am asked this question at least a dozen times a day. Last week, on the third day after receiving the last injection, a little girl stood at the triage table with a cup of milk tea and hesitated for a long time. She asked me if she could eat the butter hot pot that I had been craving for almost a month. She said that the doctor in her hometown had told her to avoid vaccination for three months, for fear that the vaccine would be in vain.

There are actually two different opinions on the duration of taboos. One is the long-circulated "taboo for 3 months or even half a year." This is actually a legacy suggestion from the early years when the purification process of domestically produced rabies vaccines was insufficient. At that time, the vaccine had many impurities and the incidence of adverse reactions after vaccination was high. Therefore, it is required to strictly avoid foods such as spicy, alcoholic, and seafood that can easily induce allergies and stimulate immune reactions to reduce the probability of discomfort. Nowadays, vaccine purification technology has been upgraded a lot, and there is no clinical basis for this long-term taboo requirement.

I once met a boy who had just entered college. When he received the second injection, he and his classmates ate very spicy maocai. The arm that was vaccinated that night was swollen and the fever reached 37.8 degrees. He went to the emergency room in the middle of the night to ask if the vaccine was useless. In fact, the spicy stimulation aggravated the local inflammatory reaction. After checking the antibody titer, it was not affected at all, so he suffered for two or three days in vain.

Of course, this does not mean that you can eat and drink as much as you want during the vaccination period. It is recommended not to touch things like alcohol that will definitely affect the immune response during the whole process. If you are allergic to seafood, mangoes and other foods, you have to avoid them regardless of whether you are vaccinated or not. If you are not allergic, there is no big problem in eating less. There is really no need to classify beef, mutton, and seafood as "forbidden items."

If you are really cautious, wait until 7 days have passed since the last injection, and your body will not experience any post-vaccination discomfort. You can smoke skewers or drink iced drinks as long as you want. There is no need to torture your mouth for unwarranted taboos, right?
